One-Part Implant with a Hydroxylated Soft Tissue Contact Surface

Abstract

One-part implant for attachment of artificial teeth comprising an anchoring part and a mounting part, wherein the anchoring part and the mounting part are configured in one piece. The anchoring part of the one-part implant has a bone contact surface B and a soft tissue contact surface S. The soft tissue contact surface S is at least partially hydroxylated or silanated, which results in an improved soft tissue integration.

1 . One-part implant for attachment of artificial teeth comprising an anchoring part and a mounting part, wherein the anchoring part and the mounting part are configured in one piece, and the anchoring part has a bone contact surface B and a soft tissue contact surface S, and the soft tissue contact surface S is at least partially hydroxylated or silanated. 
   
   
       2 . One-part implant according to  claim 1 , wherein the soft tissue contact surface S is completely hydroxylated. 
   
   
       3 . One-part implant according to  claim 1  or  2 , wherein the soft tissue contact surface S is roughened. 
   
   
       4 . One-part implant according to  claim 1  or  2 , wherein the soft tissue contact surface S is smooth. 
   
   
       5 . One-part implant according to  claim 1  or  2 , wherein the surface roughness of the soft tissue contact surface S increases towards the bone contact surface continuously or stepwise. 
   
   
       6 . One-part implant according to  claim 1 , wherein the soft tissue contact surface S is hydrophilic. 
   
   
       7 . One-part implant according to  claim 1 , wherein the soft tissue contact surface S is ceramic on an implant made of ceramic, or said soft tissue contact surface comprises a ceramic coating or a ceramic ring element. 
   
   
       8 . One-part implant according to  claim 1 , wherein the anchoring part ( 5 ) as well as the mounting part ( 20 ) are made of ceramic. 
   
   
       9 . One-part implant according to  claim 1 , wherein the implant is made of titanium, zirconium, tantalum, niobium, hafnium or alloys thereof. 
   
   
       10 . One-part implant according to  claim 1 , wherein the bone contact surface B is hydroxylated, roughened and hydrophilic. 
   
   
       11 . Method for producing a one-part implant according to  claim 1 , wherein the soft tissue contact surface S is treated with an electrolytic or chemical etching procedure until a hydroxylated surface has been produced. 
   
   
       12 . Method according to  claim 11 , wherein the soft tissue contact surface S is shot-blasted, sandblasted and/or roughened using plasma technology before treating with the electrolytic or chemical etching procedure. 
   
   
       13 . Method according to  claim 11  or  12 , wherein the chemical etching procedure is carried out with an inorganic acid or a blend of inorganic acids. 
   
   
       14 . Method according to  claim 13  wherein said inorganic acids are selected from the group consisting of hydrofluoric acid, hydrochloric acid, sulphuric acid or mixtures thereof. 
   
   
       15 . Method according to  claim 14  wherein said blend of inorganic acids is hydrochloric acid (conc.), hydrogen peroxide (conc.) and water in a weight ratio of approximately 1:1:5. 
   
   
       16 . Method according to  claim 13  wherein said blend of inorganic acids is a mixture of hydrochloric acid (conc.)/sulfuric acid (conc.)/water in a weight ratio of 2/1/1. 
   
   
       17 . Method according to  claim 11 , wherein the soft tissue contact surface S is washed with pure water which can additionally comprise additives, in an atmosphere that is inert in relation to the surface, and
 the surface, without subjection to a further treatment, is stored in an atmosphere that is inert in relation to the implant surface, and/or constantly in the presence of pure water which can comprise additional additives.   
   
   
       18 . Method according to  claim 17 , including sealing the implant in a covering which is impermeable for gases and liquids. 
   
   
       19 . Gas-tight and liquid-tight covering containing the one-part implant according to  claim 1 .
